"Routine is a comfort, comfort is a killer" is just a pompous way of saying "stay hungry" or "stay frosty" or whatever the k00l k1dz are saying these days (I guess six words about routine). Once you realize Dee Snyder said it you cease to see it as profound.

If you're on a good psychological and spiritual footing, your unconscious routine is probably great. After all, it could be argued that minimalism and asceticism allow one to focus only on the important stuff because all else has been eliminated. By not having to think about a lot of stuff, you clear your mind and your soul for more important things.
